摘要： A method performed by a network server 1436 to distribute manifest files to vehicles by: generating using a processor a first manifest file for a first system platform; sending a first notification to vehicles 1404 using the first system platform about the availability of the first manifest file; receiving a request from a first vehicle of the first plurality of vehicles for a manifest file corresponding to the first vehicle, the request including identifying information about the first vehicle; determining based on the identifying information that the first vehicle uses the first system platform; and in response sending the first manifest file to the vehicle. The method may also generate a second manifest file for a second system platform that is different from the first platform and send the second manifest file to a second vehicle of a second plurality of vehicles 1406 in the same manner. The first and second system platforms may specify a different software operating system used by vehicles, or different hardware configurations of vehicles. The first and second manifest files may specify different boot files, or different orders of execution of boot files by respective platforms.

摘要： Among other things, techniques for securely booting processors in a vehicle are described. An apparatus comprises a circuit coupled to one or more processors of a vehicle and managing a secure boot process for the processors. The circuit receives an indication that the vehicle has been powered on and sends, to a network server, a request for boot files for the processors of the vehicle. In response, the circuit receives, from the server, most recent versions of boot files respectively corresponding to the processors, wherein each boot file includes a digital signature of a trusted authority. In response to obtaining the most recent versions of the boot files, the circuit sequentially boots the processors using the respective boot files, wherein each processor executes a corresponding boot file upon verifying authenticity of the digital signature in the boot file using a corresponding class authentication key.

摘要： An apparatus comprising a circuit 1348 coupled to processors 1346 of a vehicle 1300 for managing a secure boot process for the processors and an associated method are disclosed. The circuit sends to a network server 1336 a unique identifier and in response receives from the server a manifest file including information about the boot files for execution by the processors. The circuit determines a version number for the manifest file and if valid obtains the information about the boot files from the manifest file. The circuit then determines, from the obtained information, a most recent version of each of the boot files indicated by the manifest file are locally available; and in accordance with a determination that the most recent version of the boot files are different from those locally available, obtains from a network resource the most recent versions. In response to obtaining the most recent versions, the circuit boots the processors, providing the manifest file and a most recent version of the boot file corresponding to each processor, wherein the processor executes the boot file upon verifying its authenticity.
